[V8] Replacing a 3.6 with a 4.2 - Any BTDT?

[Bastian Preindl]

Hi,

Trivia (cause you mentioned the oil cooler): We've bought the private 
Audi V8 of Mr. Tim Connolly about half a year ago in England and 
transferred it to Germany for overhauling. On the German motorway we 
accelerated to more than 130km/h and guess what happened.
The engine oil temperature rose to nearly 130°C. Surely we decreased 
speed and travelled the long way home driving only 130km/h. At home we 
found out what caused the troubles: The car simply doesn't have an oil 
cooler - where it would be expected only an oil hose coming from the 
engine and forming a loop back to the engine was found :)
It seems like cars which have been manufactured for export to countries 
which have hard speed limits like Great Britain have not been equipped 
with an oil cooler, at least the 3,6 version. However, the Audi V8 4,2 
from 1993 we've transferred and imported from Great Britain to Austria 
about three years ago was equpped with an oir cooler...

Best regards

Bastian
